* Made currency symbol standardized in Kit
* Kits should be in a standardized format.
* Having monetary rewards in kits should not break based off of a config value oriented around currency display (suffix).
* Additionally, the dollar sign should be the standard money symbol which works on all servers and should not be tied to the server's individual currency symbol.
* Note that the server's individual currency symbol will still work but probably should not be used due its volatility.
* Reworked config currency symbol parsing in Settings
* Simplifies the number of actions needed to sanitize the input.
* Now just defaults to `$` if the currency-symbol cannot be parsed.
* Removed symbol-suffixed parsing in NumberUtil#sanitizeCurrencyString
